Playing around more with eM Client I just discovered that some of my wishes are actually already a reality..!!
So, the ability to apply multiple categories to emails, contacts and events, is already availale in this remarkable software. Kudos to designers and programmers!!
However I still would like for the program to be able to automatically apply categories to messages, based on Rules.

ics files are being sent to me after a Webinar invite... when clicking on it to automatically have the event being scheduled on my calendar then... MS Outlook is opening !!! respectfully, I have displaced Outlook from being my mail client - i'd like to have that ics possibility in eMClient either.
